FIG. 1 is a schematic illustration of a water pumping device 30 according to one embodiment of the present utility model; fig. 2 is another schematic illustration of a water pumping device 30 according to one embodiment of the present utility model. Specifically, fig. 1 and 2 are side schematic perspective views of the water pump 30 in the same embodiment with the water pump 33 in the first position and in the second position, respectively.

For electrical products provided with a water pumping device and using a detachable water tank, how to install and fix the water pump is an unreliability problem. Some electrical products fix the water pump relative to the pumping device body and detach the water tank along the inclined lower part, but the water tank of the electrical products needs to consider the convenience of user operation, so that the shape and the water storage capacity of the water tank are severely limited, and the water tank can only be arranged at a high place and cannot be placed close to the ground. Some electrical products are provided with a pull-out type water tank, but the water pump needs to be suspended in the water tank by a water pipe, and the water pump can interfere with the movement of the water tank when the water tank is pulled out or pushed back each time, so that a user needs to manually adjust the position of the water pump each time, and take out or put back the water pump. Because the water pump is stained with water and even is stained with sewage, the operation of manual water taking and placing pump very influences the user and experiences the air conditioner.

In order to overcome the problem that the water pump interferes with the movement of the water tank, the conventional water pumping device often needs to be provided with a complex electric mechanism, such as an electric motor to provide power for lifting the water pump. Such an arrangement presents a number of problems, on the one hand the construction of the electric mechanism is relatively complex and, due to the limited space of the pumping device, difficult to install or clean. On the other hand, the electric motor or other parts of the electric mechanism are easily splashed or condensed, and the risk of faults is greatly increased, so that the electric mechanism is not reliable. Besides, the electric mechanism needs to additionally arrange control keys or add control logic besides the material cost of the electric mechanism, so that the production cost of the water pumping device and the air conditioner using the same can be obviously increased.

The utility model particularly provides the water pumping device 30, which can solve the problem that the water pump 33 interferes with the movement of the water tank 32 by virtue of the purely mechanical transmission mechanism 34, and does not need to introduce electric elements such as an electric motor, so that the structure of the water pumping device 30 is relatively simple, and the production cost and the cleaning difficulty are reduced.

Referring to fig. 1 and 2, the pumping device 30 of the present utility model generally includes a housing 31, a water tank 32, a water pump 33, and a transmission 34. The housing 31 has a housing chamber formed therein, and the housing chamber has an opening in a side wall of the housing 31, a water tank 32 is drawably provided in the housing chamber from the opening, and a transmission mechanism 34 is connected to the water pump 33 so that the water pump 33 is movably provided in the housing chamber. Although not specifically shown in the drawings, it can be seen from comparing fig. 1 and 2 that the opening of the housing 31 is located on the right side of the drawing, and the drawing direction of the water tank 32 also corresponds to the opening position of the housing 31.

The transmission mechanism 34 causes the water pump 33 to have a first position near the bottom of the water tank 32 and a second position that does not hinder the withdrawal of the water tank 32 from the containing chamber. The transmission mechanism 34 includes a first gear structure 341 hinged in the housing 31, and a connecting rod 342 connecting the first gear structure 341 and the water pump 33; and the rear side of the water tank 32 is provided with a second transmission structure 321. The first gear structure 341 and the second transmission structure 321 form tooth-shaped protrusions with mutually matched shapes, so that the water tank 32 drives the transmission mechanism 34 to drive the water pump 33 to move between the first position and the second position when moving.

Fig. 1 illustrates a first position of the water pump 33, and fig. 2 illustrates a second position of the water pump 33. When the water pumping device 30 is in the state shown in fig. 1, when the water tank 32 is withdrawn outwards, the second transmission structure 321 at the rear side of the water tank 32 moves forwards, and as the first gear structure 341 and the second transmission structure 321 form tooth-shaped protrusions with mutually matched shapes, the movement of the second transmission structure 321 drives the first gear structure 341 to rotate, so that the water pump 33 connected with the connecting rod 342 at the front side of the first gear structure 341 is lifted to the second position. When the water pumping device 30 is in the state shown in fig. 2, when the water tank 32 is pushed in, the second transmission structure 321 at the rear side of the water tank 32 moves backward, and after the toothed protrusions on the first gear structure 341 and the second transmission structure 321 are engaged, the movement of the second transmission structure 321 drives the rotation of the first gear structure 341 again, so that the water pump 33 connected with the connecting rod 342 at the front side of the first gear structure 341 is driven to descend to the first position.

The first gear structure 341 is hinged in the housing 31, so as to rotate in the housing 31 and drive the connecting rod 342 to swing back and forth, so that the water pump 33 moves along an arc to lift between the first position and the second position. It is generally possible to provide the first gear structure 341 with a transverse rotation shaft in the housing 31 so that the first gear structure 341 rotates around the shaft, but the first gear structure 341 is not limited to the rotation shaft as a hinge structure, and other hinge structures may alternatively be used.

The first gear structure 341 is connected to the water pump 33 through a link 342, so that the rotation radius of the water pump 33 is increased by means of the length of the link 342, and even if the second transmission structure 321 drives the first gear structure 341 to rotate only a short distance, the water pump 33 can be moved a large distance by the enlargement of the link 342, thereby moving between a first position near the bottom of the water tank 32 and a second position where the water tank 32 is not hindered from being drawn out of the accommodating chamber.

In particular, although the connecting rod 342 connects the first gear structure 341 and the water pump 33 at the same time, the connecting rod 342 needs to be fixedly connected with the first gear structure 341 so that the rotation amount of the first gear structure 341 can be transmitted to the connecting rod 342. However, the connecting rod 342 is not necessarily fixedly connected to the water pump 33, for example, the water pump 33 may be suspended at an end of the connecting rod 342 by a rope, so that the posture of the water pump 33 is kept stable, and a water pipe or a power supply line connected to the water pump 33 is not bent.

The specific arrangement of the second transmission structure 321 may be adapted according to the actual needs, for example, in some alternative embodiments, the second transmission structure 321 is a second gear structure 321 and is meshed with the first gear structure 341.

Fig. 1 and 2 illustrate, in oblique filled lines, the positions of the teeth-like projections of the first gear structure 341 and the second gear structure 321, and it can be seen that when the water pump 33 is in the first position shown in fig. 1, the positions of the teeth-like projections of the first gear structure 341 and the second gear structure 321 partially overlap, i.e., mesh with each other.

It should be noted that, for a circular gear, its teeth have an outermost tooth tip and an innermost tooth root between two teeth, and if two circular gears are meshed, the tooth tip of one gear will be opposite to the tooth root of the other gear. Thus, for two meshed circular gears, the two gear teeth are not tangent to the circle in which the two gear teeth are located, but the circle in which the one gear tooth tip is located is tangent to the circle in which the other gear tooth root is located.

Similar to the principle of circular gears, in the process of being pushed inward, the water tank 32 moves backward and is not meshed with the toothed protrusion under the first gear structure 341 when contacting with the first gear structure 341, but is abutted against the toothed protrusion in front of the first gear structure 341, and then drives the toothed protrusion to move backward to the position under the first gear structure 341, so as to drive the first gear structure 341 to rotate. The cooperation of the second gear structure 321 and the first gear structure 341 during the withdrawal of the water tank 32 is the same and will not be repeated here.

Fig. 3 is a schematic view of a water pumping device 30 according to another embodiment of the present utility model; fig. 4 is another schematic view of a water pumping device 30 according to another embodiment of the present utility model. Specifically, fig. 3 and 4 are side schematic perspective views of the water pump 30 in the same embodiment with the water pump 33 in the first position and in the second position, respectively.

Considering that, in the previous embodiment, if the gear is highly fixed, the angle by which the first gear structure 341 is rotated is very limited, and if it is desired to enable the water pump 33 to move over a wide range, it is necessary to increase the distance of the water pump 33 from the first gear structure 341 even if the connecting rod 342 is lengthened. This can greatly increase the space occupied by the transmission mechanism 34 in the direction of drawing the water pump 33, which can be too difficult for some smaller pumping devices 30.

In order to increase the rotation angle of the first gear structure 341, it is necessary to make the contact position of the second gear structure 321 with the first gear structure 341 higher and closer to the front side during the pushing of the water tank 32, for which reason, in some further embodiments, as shown with reference to fig. 3 and 4, a sliding groove is formed on the rear side of the water tank 32 in the longitudinal direction, and the second gear structure 321 is slidably disposed up and down in the sliding groove; and a spring is further provided below the second gear structure 321 for pushing the second gear structure 321 upward. As can be seen by comparing fig. 3 and 4, the second gear structure 321 has a lower height when the water pump 33 is in the first position than when the water pump 33 is in the second position.

The spring is not shown in fig. 3 and 4, but it will be appreciated that the spring provides an upward spring force under the second gear structure 321 urging the second gear structure 321 against the upper end of the chute. Since the height of the second gear structure 321 is lower when the water pump 33 is at the first position than when the water pump 33 is at the second position, when the water tank 32 is pushed in, the second gear structure 321 contacts with the first gear structure 341 at a position closer to the front side of the first gear structure 341, thereby driving the first gear structure 341 to rotate by a larger angle. During the pushing-in process of the water tank 32, the second gear structure 321 will gradually be pressed down while driving the first gear structure 341 to rotate, and slide down in the chute, and finally move from the position shown in fig. 4 to the position shown in fig. 3. During the process of drawing out the water tank 32, the second gear structure 321 is pushed upwards by the spring to move upwards, and simultaneously meshes with the first gear structure 341 and drives the first gear structure 341 to rotate.

Since the position where the second gear structure 321 contacts and separates from the first gear structure 341 is fixed, the water pump 33 can always be driven to a preset first position or second position after the water tank 32 is completely pushed in or completely pulled out.

In the above embodiment, the second gear structure 321 is not rotated, and the first gear structure 341 is fixed to the link 342 so as not to rotate. In particular, the first gear structure 341 and the second gear structure 321 are not limited to circular gears, but may be gears of other shapes, and the specific shape of the tooth-like projections may be flexibly set as needed. Further, since only a partial area of the upper side of the second gear structure 321 will be in contact with the first gear structure 341, and the first gear structure 341 does not need to rotate 360 °, in some alternative embodiments, both the first gear structure 341 and the second gear structure 321 may be part of one complete gear, or form a tooth-like protrusion only at a partial position of the gear.

Fig. 5 is a schematic view of a water pumping device 30 according to yet another embodiment of the present utility model.

In addition to the above-described embodiment in which the second transmission structure 321 is provided as the second gear structure 321, in other alternative embodiments, the second transmission structure 321 is a second rack structure 321, which is provided at the rear side of the water tank 32 in the horizontal direction, and is engaged with the first gear structure 341.

When the water tank 32 is drawn out, the second rack structure 321 moves forward, and the first gear structure 341 rotates on the second rack structure 321 by being meshed with the second rack structure 321, so as to drive the water pump 33 to move. When the water tank 32 is pushed inward, the second rack structure 321 will drive the first gear structure 341 to rotate again.

Compared with the embodiment in which the second transmission structure 321 is provided as the second gear structure 321, the second transmission structure 321 is provided as the second rack structure 321 more simply, but the rack needs to be provided along the drawing direction of the water tank 32, the length of the water tank 32 can be increased if the rack extends backward from the rear side of the water tank 32, the opening shape above the water tank 32 can be affected if the rack extends forward from the rear side of the water tank 32, and a person skilled in the art can select to provide the second transmission structure 321 as the second gear structure 321 or the second rack structure 321 according to actual needs and flexibly adjust the specific shape thereof.

In order to maintain the water pump 33 in the second position during withdrawal of the water tank 32, in some alternative embodiments, the water pumping device 30 further includes a resilient structure 35, the resilient structure 35 being disposed within the housing 31 and coupled to the linkage 342 for moving the water pump 33 toward the second position.

The resilient structure 35 is preferably a spring, that is to say by the spring pulling the link 342, ensuring that the water pump 33 is maintained in the second position. The elastic structure 35 may be a coil spring, or may be a hydraulic pump, a pneumatic pump, or the like having a telescopic function. The resilient structure 35 is configured such that the pulling force is balanced just when the water pump 33 is in the second position, i.e. the resilient force of the resilient structure 35 just counteracts the weight of the water pump 33 when the water pump 33 is in the second position.

Considering the problem that the elastic structure 35 may deteriorate due to aging, if the water pump 33 is pulled by the elastic structure 35 alone, the water pump 33 may not return to the second position after a long period of use of the water pump 30. Thus, in some alternative embodiments, the pump assembly 30 further includes a stop structure 36, the stop structure 36 being disposed above the link 342 or the pump 33, and the stop structure 36 abutting the link 342 or the pump 33 when the pump 33 is in the second position, thereby preventing the pump 33 from moving upward from the second position.

By providing the stop structure 36 at a suitable position, it is not necessary to strictly provide the elastic structure 35 with moderate elasticity to ensure that the water pump 33 is stable and not moving at the second position, but the tension of the elastic structure 35 can be increased to a certain extent, and even if the elastic structure 35 ages, it can be ensured that the elastic structure 35 has enough tension to pull the connecting rod 342 or the water pump 33 to a position abutting against the stop structure 36, thereby prolonging the service life of the water pumping device 30 and improving the stability of the operation of the water pumping device 30.

In addition to the above-described embodiment in which the elastic structure 35 is provided, the first gear structure 341 may alternatively be provided with a locking piece that is reversibly fixed at a position below the first gear structure 341 that does not collide with the second transmission structure 321, and when the water tank 32 is completely pushed in, a first end of the locking piece is lifted by a rear side wall of the water tank 32, thereby causing the second end to be pushed down to be separated from the first gear structure 341. When the water tank 32 is drawn out and the first gear structure 341 is just separated from the second transmission structure 321, the rear side wall of the water tank 32 does not lift the first end of the locking piece any more, the second end of the locking piece is lifted up under the elastic action (which can be realized by arranging a coil spring) and is contacted with the first gear structure 341, and by arranging a clamping structure such as a buckle at the contact position between the locking piece and the first gear structure 341, the first gear structure 341 can be ensured not to rotate during the drawing out of the water tank 32.

To prevent the water tank 32 from accidentally moving outwardly, in some alternative embodiments, the water pumping device 30 further includes a tank mount 37, the tank mount 37 controllably connecting and securing the water tank 32 and the housing 31 for preventing the water tank 32 from moving outwardly of the receiving chamber.

The tank fixing member 37 may be a sliding latch that simply and conveniently latches the tank 32 to prevent the tank 32 from moving outward. In addition, the tank fixing member 37 may be provided in other configurations, which are not limited herein.

To facilitate the user to determine how much water remains, the front panel of the water tank 32 may be provided as a transparent plate, or a transparent plate in a strip shape may be provided on the front panel of the water tank 32 in the longitudinal direction.

Fig. 6 is a schematic view of an air conditioner indoor unit 20 according to one embodiment of the present utility model; fig. 7 is a schematic block diagram of an air conditioner 10 according to one embodiment of the present utility model.

Referring to fig. 6 and 7, the pumping device 30 of the present utility model may be applied to an air conditioner 10 and provided at an air conditioner indoor unit 20, and the air conditioner 10 generally includes the air conditioner indoor unit 20 provided indoors and the air conditioner outdoor unit 40 provided outdoors, which are connected through a refrigerant pipe, and the pumping device 30 is capable of supplying water to a humidification module or an air purification module of the air conditioner indoor unit 20. The water pumping device 30 may be integrated into the indoor unit 20, for example, in some embodiments, the housing 31 of the water pumping device 30 is part of the housing 31 of the indoor unit 20, and in some embodiments, the housing 31 of the water pumping device 30 is detachably disposed with other parts of the indoor unit 20. The air conditioner indoor unit 20 generally has an air outlet provided at an upper portion, and a water pumping device 30 provided at a bottom portion and forming a receiving chamber to receive a water tank 32. The user also needs to operate at a low level to access the water tank 32.

The pumping device 30 is generally defined as its front side, that is, the opening of the pumping device 30 is opened on the front side wall of the housing 31. In most cases, the front side of the water pumping device 30 is located on the same side as the air outlet of the air conditioner indoor unit 20 for convenience of user operation, that is, the front side of the water pumping device 30 is the front side of the air conditioner indoor unit 20, but the front side of the water pumping device 30 may be located on one lateral side or the rear side of the air conditioner indoor unit 20 according to the arrangement of the air conditioner indoor unit 20.

Because the water pumping device 30 of the utility model can automatically lift the water pump 33 along with the drawing and pushing of the water tank 32, no additional opening is needed to be arranged above the drawing opening matched with the water tank 32 in size so that hands can extend into the air conditioner 10, the aesthetic property of the air conditioner 10 is greatly improved, the layout of the front panel of the air conditioner 10 is more reasonable, the air outlet can occupy a larger space of the front panel of the air conditioner 10 in the longitudinal direction, and the air outlet area is not needed to be reduced in order to keep the space for manually adjusting the water pump 33.

In addition to the application to the air conditioner 10, the water pumping device 30 of the present utility model may be applied to an air humidifier or other electrical products requiring the provision of a pull-out water tank 32 for water supply, as is not illustrated herein.

By now it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the utility model have been shown and described herein in detail, many other variations or modifications of the utility model consistent with the principles of the utility model may be directly ascertained or inferred from the present disclosure without departing from the spirit and scope of the utility model.
